Android updates are normally received OTA (Over The Air), that is, sent directly to your Android phone without the need for a computer. Normally, once your Android phone or tablet is due to get an upgrade, you'll see a notification in the bar at the top of the screen. You'll then be prompted to connect to WiFi to avoid incurring extra data charges - updates can be quite big and downloading them over a mobile data connection isnít advised as it may result in expensive data charges.
